Application August 25, 1930, Serial No. 477,668 Renewed April 19, 1933 3 Claims.

This invention relates to improved means for holding packages of yarn in place for dyeing, bleaching and otherwise treating the same and more especially relates to means for properly holding the yarn in such a position as to cause the dyestuff, bleaching agent, drying agent or other fluids to be passed evenly through all portions of the yarn and also it relates to means for properly holding the yarn under suitable pressure to cause the packages of yarn to occupy a position so as to prevent leakage of the dyestuif, bleaching agent or other fluids by passing through the junction point of the packages of yarn more freely than at other points in the package of yarn.

An object of our invention is to provide means for holding packaged yarn in place while the same is being dyed, bleached or otherwise treated by providing means for quickly securing the upper- 29 most portions of the holders for the yarn in position and causing the pieces of yarn to be held in proper position to abut against each other and to close the space between the end portions of the yarn, or the cores on which the yarn is wound.

Another object of our invention is to provide a yarn holder for treating packaged yarn in which means are provided for securing all of the upper ends of the yarn holders in position and applying resilient means to the upper ends of the yarn 30 holders and the packages of yarn thereon to cause the ends of the packages of yarn to fit firmly against each other and prevent leakage of the treating fluid between the adjoining surfaces of the packages of yarn and cores on which the yarn is wound so that when the treating fluid is passed through the yarn it will be forced through the perforated cores and the yarn evenly, and will not be allowed to leak through the adjoining surfaces of the various packages of yarn.

Some of the objects of our invention having been stated other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which- Figure 1 is a side elevation of the yarn holding means showing the same in position in a suitable container which container is shown mostly in cross-section;

Figure 2 is a cross-sectional view taken along the line 2-2 in Figure 4 and showing certain portions in cross-section and other portions in elevation;

Figure 3 is a top plan view of the manifold into which the perforated pipes are secured;

55 Figure 4 is a plate plan view of the top member adapted to be fitted above the upper ends of the perforated pipes;

Figure 5 is an enlarged detailed view partly in cross-section showing the upper end of one of the perforated pipes with the compression means associated therewith;

Figure 6 is a bottom plan view of the spring shown in upper portion of Figure 5.

Referring more specfically to the drawings, we show our device in Figure 1 enclosed within a kier of a dyeing machine having a body portion 10 and top portion 11, said parts being secured together by means of bolts 12 and a lid portion 13 having a resilient member 14 to press against the plate 51 to seat ring 27 in its seat 21. Secured to the body portion 10 by means of bolts 15 is a manifold bottom portion comprising a passageway 17 and a false bottom member 18 with holes 19 therethrough for the liquid to pass into or out of a chamber 20 and the passageway 17 has a lead seat portion 21 therearound. The above described mechanism is shown and described for the purpose of illustrating one method of using the improved structure which comprises a manifold 25 having a passageway 26 in the central portion thereof and circular sidewall 27 of this passageway 26 is adapted to fit on the lead seat 21. This member 25 has a cavity 28 extending equal distances entirely around the central passageway 26 and integral with the portion 25 is a top portion 29 which has a plurality of bosses 30 integral therewith through which threaded holes 31 are provided registering with the cavity 28. A central boss 32 is provided in which is secured a central shaft 33 by means of said shaft having a tapering portion 34 penetrating the portion 27 and secured in place by means of nut 35.

In each of holes 31 is threadably secured a perforated pipe 36 and around the periphery of the portion 29 is a plurality of notches 37 into which the elongated bolts 38 are adapted to fit and to be tightened in position by means of nut 39 on the lower end thereof and nut 40 on the upper end thereof. Onto these perforated upstanding pipes 36 the packages of yarn 42 are adapted to be stacked and in the left hand portion of Figure 2, we show cores 41 with washers 59 therebetween so as to form a liquid tight joint between the cores and to cause the liquid to be passed under pressure out through the cores 41 and through yarn 42 thereon or in the reverse direction. The upper end of each of the perforated pipes 36 is plugged with a threaded member 43 having a hole 44 centrally disposed therein in which is slidably mounted a rod which rod 45 has a plug 46 threadably secured thereon which has a central projecting portion 4'7 which is adapted to fit within the upper end of core 41. The rod 45 extends upward above the upper surface of member 46 and has a compression spring 48 secured thereon by means of said compression spring being drawn into a circular portion 49 of a suitable size to fit around the threaded portion of rod 45 and a nut 50 is secured on the upper end of said rod 45 to secure the compression spring 48 in posi tion.

The cores 41 on which the yarn is wound vary in length and instead of providing separate means for causing the cores 41 to fit firmly against the fiber washers or to cause the yarn on the cores to fit firmly against each other if the yarn bulges from the end of any of the cores, we have provided means for causing the cores to fit snugly against the fiber washers, said means comprising a plate 51 having a plurality of bosses 52 thereon with reenforcing ribs 53 on the upper side thereof and eyes 54 and 55 are threadably secured in plate 51 by means of which the plate 51 and also the entire package container can be porperly handled.

Around the periphery of plate 51 we provide a plurality of notches 56 into which the elongated bolts 38 are adapted to fit and to be secured into position by tightening the nuts 40 or the nuts 39. The lower surface of the plate 51 has a plurality of circular cavities 58, there being a cavity for each of the bosses 52 adapted to coincide with the upper end of each of the perforated pipes 36. These cavities 58 are adapted to coincide also with the compression springs 48 placed above each of the perforated pipes 36 and when the member 51 is placed in position and the compression springs are resting in the cavities 58 the nut 60 on the upper end of shaft 33 is driven home and rods 38 secured in position to cause the compression springs 48 to press downwardly to force plugs 46 against the: upper end of the uppermost core 41 and this will automatically cause all of the cores on each of the perforated pipes to fit snugly against the washers 59 between adjoining ends of the cores and this will cause an even distribution of the pressure throughout the entire length of the yarn on the perforated pipes and will cause an even flow of the liquid through all portions of the yarn.

It is of course evident that the liquid will be forced upwardly through pipe 1 into chamber 17 and up through passageway 26 into circular cavity 28 and up through each of the perforated pipes 36, out through the perforation on the cores 41, through the yarn and back downwardly on top of the member 29 and after falling off the edge of 29 the liquid will pass through the holes 19 and be retiu'ned to the system through the pipe 2. The above described fiow in the operation is intermittently reversed.

Another advantage of our invention is that, in case a non-rigid core should be used, by having the compression springs 48 pressing at all times against the uppermost package of yarn, it will cause the yarn at all times to adjust itself to any change of conditions which might occur during the treatment of the packages by forcing of liquor therethrough. It is evident that where each stack of packages is adjusted individually before the treating operation occurs that during the treating operation if a non-rigid core were used certain parts of the yarn might collapse and cause a leakage between the adjoining portions of packages and this would cause undue leakage between these two packages of yarn and would not cause the proper amount of liquor to be passed through the other packages but by providing the compression springs 48 at all times pressing downwardly on the packages of yarn it would cause any' leak which might break between adjoining packages of yarn to be automatically st opped by the constant pressure which is applied to the packages of yarn on the perforated pipes.

Another advantage of our arrangement is that the plate 51 protects the upper ends of the per forated pipes 36 and prevents undue breakage of the same while being handled.

One advantage of securing all of the perforated pipes together is that it facilitates handling of the holder, from one part of a processing machine to another such as transferring the same from the kier to the extracting or drying chamber and the placing of the package holder in the kier and also removing it from the drying or extracting chamber.

In the use of rigid cores on which the yarn is wound, it is well known that the length of the cores vary and were it not for the resilient means which we employ, individual securing means must be employed on the upper end of each of the perforated pipes to insure that all cores fit against the washers therebetween, and in Figure 2, the two outside stacks of yarn are shorter than the two inside stacks, and there it is shown how the resilient means at the top of the stacks automatically cause the cores to fit snugly against each other, regardless of the aggregate height of the cores on a particular perforated pipe.

In the drawings and specification we have set forth a preferred embodiment of our invention, and although specific terms are employed they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of our invention being set forth in the appended claims.
